  • is Checkland's approach still relevant today?

    - by WeNeedAnswers
    I remember back in the mid 90's that I came across a systems methodology called Checkland's Approach or sometimes called SSM (Soft Systems Methodology). With the advent of Agile and Extreme Programming, not to mention some of the harder methodologies and methods out there related to Object technologies. Is the use of such a methodology still relevant in today's world?

  • Move Physical Windows Server 2008 into a Hyper-V VM

    - by Randall Sexton
    Hello, I'd like to import a real Windows Server 2008 server as a Hyper-V Virtual Server on another Windows Server 2008 instance. Anyone have any idea how to do this? I'm looking at the System Center Virtual Machine Manager 2008 but it doesn't seem to import Windows Server 2008 - nor is it free. Is there some other workaround (i.e. import the image into VMWare first, then convert to Hyper-V)? Please help. Regards, Randall

  • What is the difference between moveBackward: and moveLeft: when using NSResponder -interpretKeyEvent

    - by nciagra
    I'm implementing a custom text box using -interpretKeyEvents: and am trying to figure out what the difference is between moveBackward: vs moveLeft: and moveForward: vs moveRight:. moveLeft: is bound to the left arrow and moveBackward: is bound to Ctrl + B. The documentation describes them almost identically and they seem to behave identically in practice. I'm assuming this is just a holdover from Vim? Does anyone know what the real difference is? Should moveBackward: just call my moveLeft: implementation? Thanks a lot, Nick

  • How to get a good price on dev books

    - by mgroves
    Does anyone have any tips for getting a good price on new/used programming-related books? I've looked at some of the more popular books (like DDD and GoF), and even used they can be pretty pricey. I'm not saying they aren't worth it, but I feel like there might be a more focused book store or exchange or something just for devs and/or IT professionals that I just don't know about. Any tips at all would be appreciated.

  • enCapsa -what is it and what is used for?

    - by agnieszka
    It may not be a pure programming question but I'm looking for information about enCapsa. Do you know what it is, have you ever used it? I'm reading some papers about it but I can't really see how it works and what it can be used for in an IT company (and this is what i am supposed to find out).

  • Regex: How do I match some regex logic 1 or more times?

    - by tom
    I already have some regex logic which says to look for a div tag with class=something. However, this might occur more than once (one after another). You can't simply add square brackets around that complex regex logic already (e.g. [:some complicated regex logic already existing:]* -- so how do you do it in regex? I want to avoid having to use the programming language logic to append that regex logic after itself if I can... Thanks

  • Notification in case of data changes in SQL and Oralce

    - by user171523
    I am in the process of building a system where i need to notify a Window Service a .net based application in case of any change in the DB table (Insert , Update , Delete). I know this can be done with the ADO.NET Events in SQL. Is there any common solution for Oracle and SQL which can provide this kind of notifications. This needs to happen as and when the update happens on real time basis.

  • why develop in windows/desktop application?

    - by Alexander
    Just wondering what your comments are regarding the current trend as everything is moving to the web or even the cloud. The significance of an OS or desktop application is getting less attention than web application. So to those folks out there who still develop windows applications, such as WPF. Why still do it? Why not move to web programming? Silverlight instead for example...

  • Which tool do you use for tracking daily/weekly progress on your long-term goals?

    - by NoCatharsis
    I read through this post and this post to get an idea of short-term task management applications out there. However, now I'm having a problem tracking my longer-term goals pertaining to things like career, education, and exercise. I just discovered Disciplanner which might meet my needs but haven't had time to set it up just yet. Not to mention, it took me about 2 weeks of playing with every online to-do list app I could find before I came to a decision on which to use. I'm very particular about my tasks and goal-setting, so I would prefer to get some advice from other superusers before diving into the web again to find another life-management website.

  • Stack Trace of cross-thread exceptions with Invoke

    - by the_lotus
    When an exception happens after calling Invoke, .NET shows the stack trace as if the error happens while calling Invoke. Example below: .NET will say the error happen in UpdateStuff instead of UpdateStuff - BadFunction Is there a way to catch the "real" exception and show the correct stack trace? Private Sub UpdateStuff() If (Me.InvokeRequired) Then Me.Invoke(New UpdateStuffDelegate(AddressOf UpdateStuff)) Return End If Badfunction() End Sub Private Sub BadFunction() Dim o As Object o.ToString() End Sub

    Hello everyone, My database has two types of entries: The very dynamic (users, comments, etc) and the more static (email templates, flat-pages). During testing I want a clean DB but with the real 'semi-static' data. Is there a way to make Django's testing system to load parts of the original DB ? Thanks

  • MacBook Pro - 72k vs 54k rpm drives - Heat and Noise

    - by webworm
    I am looking at a new 15" MacBook Pro for development purposes. I am planning to run a Virtual Machine for about 50% of my work (Windows 7 x64, IIS, SQL Server, and VS 2010). The upgrade from a 54000 rpm drive to a 72000 rpm is only $45. From what I understand the faster rotational speed of the 72000 rpm drive will help virtual machine performance. However, I am concerned that additional heat and fan noise might be an issue. I will be running mostly on A/C power so decreased battery life is not a major concern for me. Since I would be running with a Core i7 processor which gives off a fair amount of heat already I was wondering if it might be best to stay at 54000 rpm for the hard drive. What do you all think? Thanks!

  • Programmers joy: the proccess or the result?

    - by faya
    Hello, Recently I stumbled upon this curious question: What is importing for yourself when programming: process or result? I found myself that I love outcome, when everything is done! So I tried to ask some colleagues at work, but all of them responded that they like the development process the most. Myself I like process too, but not as much as outcome. So to which people category you belong too? And if there is a reason, could you express why?

  • starting nginx via upstart

    - by Chiggsy
    Background: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS" I've built nginx, and I'd like to use upstart to start it: nginx upstart script from the site: description "nginx http daemon" start on runlevel 2 stop on runlevel 0 stop on runlevel 1 stop on runlevel 6 console owner exec /usr/sbin/nginx -c /etc/nginx/nginx.conf -g "daemon off;" respawn I get "unknown job" when i try to use initctl to run it, which I just learned apparently means there is an error, ( what's wrong with "Error" to describe errors?) Can someone point me in the right direction ? I've read the documentation , as it is, and it seems kind of sparse for a SysV init replacement... but whatever just need to add this job to the list, run it, and get on with what's left of my life... Any tips? EDIT: initctl version init (upstart 0.6.5)
